Abstract
A method for restoring an image of a fingerprint sensor is described. The method includes capturing, by the fingerprint sensor, a fake fingerprint image from a fake fingerprint; calculating a phase of the fake fingerprint from the fake fingerprint image; capturing a plurality of target fingerprint images at measurement times by a fingerprint sensor disposed on a rear side of a display panel; applying the calculated phase to each of the acquired target fingerprint images; and combining information from each of the plurality of target fingerprint images to generate a final fingerprint image.
